风控引擎服务 — RiskEngineService 技术方案与当前实现说明
|
||
================================================================================
|
||
|
||
【项目背景】
|
||
当前 TRS 系统已在 QuotaMonitorService 中接入第一版风控引擎，用于在交易关键
|
||
时点执行可配置规则判断。当前目标不是一次性做成最终版，而是在最小可运行链路
|
||
跑通后，逐步演进为可由前端配置、后端预编译、执行期直接命中的正式版本。
|
||
|
||
【当前实现口径】（以本注释和实际代码为准）
|
||
|
||
核心概念：
|
||
- RiskRule（风控规则）：规则定义本体，当前重点字段包括 Id、RuleName、
|
||
RuleText、RuleExpr、Version、CompiledScript。
|
||
- RiskRuleApplication（规则应用）：与规则分离，承载启用状态、控制策略、触发时点、
|
||
适用范围（全局 / 账户 / 客户 / 标的类型 / 合约类型）。
|
||
- RuleExpr：当前唯一主编译入口。要求内容是 Roslyn 可直接执行的 C# bool 表达式，
|
||
例如通过 DbContext 和 TradeId 查询数据库后做数值或日期比较。
|
||
- ConditionJson：当前已在规则定义中保留，但不参与主执行链路。
|
||
- RiskContext：一次风控检查的数据上下文，包含 TradeId、TriggerPoint 和 DbContext。
|
||
- RuleCompiledCache：进程内编译结果缓存，按规则 Id 缓存 Func<RiskContext, bool>。
|
||
|
||
当前编译流程：
|
||
1. 外部准备好规则对象，在 RuleExpr 中直接写最终可执行表达式
|
||
2. 调用 RuleCompiler.ValidateAndCompileRule(rule)
|
||
3. 内部使用 Roslyn 编译 RuleExpr，生成 Func<RiskContext, bool>
|
||
4. 编译成功后写入 rule.CompiledScript，并同步写入 RuleCompiledCache
|
||
5. 执行阶段优先从 RuleCompiledCache 取委托执行
|
||
|
||
当前执行流程（EvaluateRisk）：
|
||
1. 从数据库加载规则列表和应用列表
|
||
2. 按应用状态、TriggerPoints 过滤有效应用
|
||
3. 按应用范围过滤交易是否命中（全局 / 账户 / 客户 / 标的类型 / 合约类型）
|
||
4. 根据应用配置中的 RuleIds 找到对应规则 Id 并关联规则
|
||
5. 优先从 RuleCompiledCache 读取已编译委托，未命中时兜底编译一次
|
||
6. 执行规则委托，按 ControlStrategy 聚合为 Blocked / NeedApproval / Warnings
|
||
7. 返回 RiskResult
|
||
|
||
当前维度匹配规则：
|
||
- 全局：ScopeIsGlobal=true 时直接命中
|
||
- 同一维度内多选：并集（OR）
|
||
- 不同维度之间：交集（AND）
|
||
- 某维度留空：视为该维度不限制
|
||
|
||
【与早期方案的主要差异】
|
||
- 当前不是 Content 解析或表达式树主导，而是 RuleExpr 直编译主导
|
||
- RiskRule 与 RiskRuleApplication 当前仍是分离模型，没有合并
|
||
- 编译器文件已放入 RiskEngine/Compile 目录下
|
||
- 当前已引入 RuleCompileResult、RuleCompiledCache，用于校验结果与进程内缓存
|
||
- Rule2 这类“左值与右值都来自对象字段”的规则，当前通过 RuleExpr 直接表达
|
||
|
||
【当前代码结构】
|
||
风控引擎层：YLErpDAL/Modules/RiskEngine/
|
||
- RiskEngineService.cs：执行入口，负责规则筛选、应用过滤、委托执行、结果聚合
|
||
- RiskRule.cs：规则定义模型，含 CompiledScript 运行时字段
|
||
- RiskRuleApplication.cs：规则应用模型，承载策略、触发点和适用范围
|
||
- RiskContext.cs / RiskResult.cs：执行上下文与结果模型
|
||
|
||
编译相关：YLErpDAL/Modules/RiskEngine/Compile/
|
||
- RuleCompiler.cs：Roslyn 编译入口，提供 ValidateAndCompileFormula / ValidateAndCompileRule
|
||
- RuleCompileResult.cs：编译结果模型
|
||
- RuleCompiledCache.cs：编译结果缓存
|
||
|
||
当前集成点：
|
||
- QuotaMonitorService.cs：构造 RiskContext，并传入当前 TradeId
|
||
|
||
【当前进度】（截至 2026-06-24）
|
||
✅ 已完成：
|
||
1. RiskEngine 第一版执行链路已跑通：QuotaMonitorService -> RiskEngineService -> RuleCompiler
|
||
2. 风控上下文提供 DbContext 和 TradeId，支持规则脚本直接查询数据库
|
||
3. RuleExpr 直编译方案已接入，支持数值比较和日期比较
|
||
4. Application 通用维度匹配已支持：全局 / 账户 / 客户 / 标的类型 / 合约类型
|
||
5. 维度组合逻辑已按文档确认：同维度 OR，不同维度 AND
|
||
6. RuleCompiler 已支持校验 + 编译 + 写缓存
|
||
7. RuleCompiledCache / RuleCompileResult 已落地到 Compile 目录
|
||
8. RiskEngineService 已改为执行时优先从 RuleCompiledCache 读取委托
|
||
|
||
【待办事项 / TODO】
|
||
⬜ 1. 接入真实规则来源
|
||
- 由数据库或前端提交替换当前 LoadRules / LoadApplications 的规则来源
|
||
⬜ 2. 增加接口层
|
||
- 提供前端提交 RuleExpr 后的校验接口
|
||
- 提供规则保存 / 发布后预编译并写缓存的入口
|
||
⬜ 3. 启动预热与缓存刷新
|
||
- 服务启动时批量加载有效规则并预编译
|
||
- 支持规则更新后的缓存刷新 / 删除
|
||
⬜ 4. 完善执行期策略
|
||
- 当前保留“缓存未命中时兜底编译”逻辑
|
||
- 后续可收紧为“执行期只读缓存，未命中按发布失败处理”
|
||
⬜ 5. 补测试样例
|
||
- 数值比较、日期比较、维度过滤、非法公式、边界值
|
||
⬜ 6. 完善 RuleExpr 配套能力
|
||
- 提供前端可用的表达式编辑、校验与错误提示
|
||
- 约束可用变量、类型转换和脚本安全边界
|
||
|
||
【注意事项】
|
||
1. 当前 RuleExpr 必须是 Roslyn 最终可执行的 C# bool 表达式，不是业务语义短句
|
||
2. RuleExpr 可直接使用 DbContext 查询数据库，当前交易通过 TradeId 定位
|
||
3. 当前缓存的是 Func<RiskContext, bool>，这是规则判断函数，不是事件处理器
|
||
4. 业务可预期失败优先走结果返回，不要把高频校验失败都设计成异常
